<p>我们目前的系统存在诸多子系统，而这些子系统是分别部署在不同的服务器中，那么使用传统方式的session是无法解决的，我们需要使用相关的单点登录技术来解决。</p>
<p><img src="https://pluto-1300780100.cos.ap-nanjing.myqcloud.com/img/image-20200921225012413.png" alt="image-20200921225012413"></p>
<p>SSO单点登录访问流程主要有以下步骤：</p>
<ol>
<li>访问服务：SSO客户端发送请求访问应用系统提供的服务资源。</li>
<li>定向认证：SSO客户端会重定向用户请求到SSO服务器。</li>
<li>用户认证：用户身份认证。</li>
<li>发放票据：SSO服务器会产生一个随机的Service Ticket。</li>
<li>验证票据：SSO服务器验证票据Service Ticket的合法性，验证通过后，允许客户端访问服务。</li>
<li>传输用户信息：SSO服务器验证票据通过后，传输用户认证结果信息给客户端。</li>

<h2 id="2-什么是CAS"><a href="#2-什么是CAS" class="headerlink" title="2.什么是CAS"></a>2.什么是CAS</h2><p>CAS 是 Yale 大学发起的一个开源项目，旨在为 Web 应用系统提供一种可靠的单点登录方法，CAS 在 2004 年 12 月正式成为 JA-SIG 的一个项目。CAS 具有以下特点：</p>
<p>【1】开源的企业级单点登录解决方案。<br>【2】CAS Server 为需要独立部署的 Web 应用。<br>【3】CAS Client 支持非常多的客户端(这里指单点登录系统中的各个 Web 应用)，包括 Java, .Net, PHP, Perl, Apache, uPortal, Ruby 等。</p>
<p>从结构上看，CAS 包含两个部分： CAS Server 和 CAS Client。CAS Server 需要独立部署，主要负责对用户的认证工作；CAS Client 负责处理对客户端受保护资源的访问请求，需要登录时，重定向到 CAS Server。</p>
<h2 id="3-CAS服务端"><a href="#3-CAS服务端" class="headerlink" title="3.CAS服务端"></a>3.CAS服务端</h2><h3 id="3-1部署"><a href="#3-1部署" class="headerlink" title="3.1部署"></a>3.1部署</h3><p>Cas服务端其实就是一个war包。在cas-server-4.0.0-release\cas-server-4.0.0\modules目录下。</p>
<p>将其改名为cas.war放入tomcat目录下的webapps下。启动tomcat自动解压war包。浏览器输入<a target="_blank" rel="noopener" href="http://localhost:8080/cas/login">http://localhost:8080/cas/login</a> ，可看到登录页面</p>
<h3 id="3-2端口修改"><a href="#3-2端口修改" class="headerlink" title="3.2端口修改"></a>3.2端口修改</h3><p>打开tomcat 目录 conf\server.xml，修改tomcat的端口为9100</p>
<p>修改cas的WEB-INF/cas.properties </p>
<pre class="line-numbers language-properties" data-language="properties"><code class="language-properties"><span class="token attr-name">server.name</span><span class="token punctuation">=</span><span class="token attr-value">http://localhost:9100</span><span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
<h3 id="3-3去除https认证"><a href="#3-3去除https认证" class="headerlink" title="3.3去除https认证"></a>3.3去除https认证</h3><p>CAS默认使用的是HTTPS协议，如果使用HTTPS协议需要SSL安全证书（需向特定的机构申请和购买） 。如果对安全要求不高或是在开发测试阶段，可使用HTTP协议。我们这里讲解通过修改配置，让CAS使用HTTP协议。</p>
<p>（1）修改cas的WEB-INF/deployerConfigContext.xml</p>
<p>找到下面的配置</p>
<pre class="line-numbers language-markup" data-language="markup"><code class="language-markup"><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>bean</span> <span class="token attr-name">class</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler<span class="token punctuation">"</span></span>
<span class="token attr-name"><span class="token namespace">p:</span>httpClient-ref</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>httpClient<span class="token punctuation">"</span></span><span class="token punctuation">/&gt;</span></span><span aria-hidden="true" class="line-numbers-rows"><span></span><span></span></span></code></pre>
<p>这里需要增加参数p:requireSecure=”false”，requireSecure属性意思为是否需要安全验证，即HTTPS，false为不采用</p>
<p>（2）修改cas的/WEB-INF/spring-configuration/ticketGrantingTicketCookieGenerator.xml</p>
<p>找到下面的配置</p>
<pre class="line-numbers language-markup" data-language="markup"><code class="language-markup"><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>bean</span> <span class="token attr-name">id</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>ticketGrantingTicketCookieGenerator<span class="token punctuation">"</span></span> <span class="token attr-name">class</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>org.jasig.cas.web.support.CookieRetrievingCookieGenerator<span class="token punctuation">"</span></span>

      <span class="token attr-name"><span class="token namespace">p:</span>cookieMaxAge</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>-1<span class="token punctuation">"</span></span>
      <span class="token attr-name"><span class="token namespace">p:</span>cookieName</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>CASTGC<span class="token punctuation">"</span></span>

<p>参数p:cookieSecure=”true”，同理为HTTPS验证相关，TRUE为采用HTTPS验证，FALSE为不采用https验证。</p>
<p>参数p:cookieMaxAge=”-1”，是COOKIE的最大生命周期，-1为无生命周期，即只在当前打开的窗口有效，关闭或重新打开其它窗口，仍会要求验证。可以根据需要修改为大于0的数字，比如3600等，意思是在3600秒内，打开任意窗口，都不需要验证。</p>
<p>我们这里将cookieSecure改为false , cookieMaxAge 改为3600</p>
<p>（3）修改cas的WEB-INF/spring-configuration/warnCookieGenerator.xml</p>
<p>找到和上面差不多的修改cookieSecure改为false , cookieMaxAge 改为3600</p>
<h3 id="3-4数据源设置"><a href="#3-4数据源设置" class="headerlink" title="3.4数据源设置"></a>3.4数据源设置</h3><p>我们现在让用户名密码从我们的品优购的user表里做验证</p>
<p>（1）修改cas服务端中web-inf下deployerConfigContext.xml ，添加如下配置</p>
